Abstract:Fatigue problem has been an important issue in aeropropulsion system composite structures due to acoustic pressure, vibration and hostile environments. Various forms of damage caused by fatigue loadings can degrade the structural properties. This Phase I research proposes a combined BEM/FEM approach… more
Abstract:FIELD PROGRAMMABLE GATE ARRAYS (FPGAS) AND FIELD PROGRAMMABLE INTERCONNECT DEVICES (FPIDS) HAVE THE ABILITY TO INTEGRATE THOUSANDS OF LOGIC GATES ON A SMALL BOARD IN WHICH THE INTERCONNECTIONS CAN BE COMPLETELY REARRANGED WITHIN MILLISECONDS WITHOUT MANUAL EFFORT. USING FPGAS AND FPIDS, IT IS NOW… more
Abstract:The objective of this work is the development of 3 - 5 micron sensors operating at temperatures from 30C to 70C, for use in Space-Based Surveillance Systems without the use of Cryo-coolers, or uncooled. It is based on a major breakthrough achieved at Xacton. This has led to the fabrication of wafers… more
Abstract:ARRAYS OF ENERGY-DISPERSIVE X-RAY DETECTOR ARRAYS ARE HEAVILY USED IN BIOLOGICAL RESEARCH AT SYNCHROTRON RADIATION FACILITIES, PARTICULARLY FOR ABSORPTION SPECTROSCOPY IN FLUORESCENCE MODE ON DILUTE SAMPLES BECAUSE AN INDIVIDUAL SEMICONDUCTOR SPECTROMETER TYPICALLY BECOMES PILEUP LIMITED AT 40-80… more
Abstract:Energy-dispersive x-ray detectors (EDDs) are heavily used in biological research at synchrotronradiation facilities, particularly for absorption spectroscopy in fluorescence mode on dilute samples.Current research relies on semiconductor EDD spectrometers, which typically become pileup limited… more
Abstract:THE PHOTOMULTIPLIER TUBE (PMT). CONSISTING OF A PHOTOCATHODE AND A DYNODE BASED ELECTRON MULTIPLIER (EM), IS AN IMPORTANT ELECTRO-OPTIC DEVICE IN A VARIETY OF RADIATION MEASUREMENTS. IT IS A VERSATILE AND SENSITIVE DETECTOR WITH LOW NOISE AND FAST RESPONSE TIME. THE EM DYNODE STRUCTURES, HOWEVER,… more
Abstract:Xinotech proposes to research and develop a knowledge-based, metalanguage-generated environment with homogeneous support for rapid prototyping of hard real-time embedded systems using Luqi's PSDL as the executable prototyping language and for the subsequent deployment to various distributed and… more
Abstract:INVESTIGATORS ARE RESEARCHING AND DEVELOPING TECHNOLOGY FOR A LANGUAGE-BASED, LANGUAGE-INDEPENDENT, FORMALLY-GENERATED, ATTRIBUTE GRAMMAR-BASED, INTERACTIVE PROGRAMMING ENVIRONMENT, COMMERCIALLY AVAILABLE FOR ADA, CMS-2, MODULA-2, AND COBOL. THEY ARE DEVELOPING A KNOWLEDGE-BASED, METALANGUAGE-BASED… more
Abstract:A SIMPLE POWDER MARKING PROCESS KNOWN AS DIRECT ELECTROSTATIC PRINTING (DEP) WAS INVENTED TO ENABLE THE DEVELOPMENT OF AFFORDABLE DESKTOP COLOR PRINTERS. THE PROCESS PROVED TO BE CAPABLE OF PRINTING IMAGES WITH 12 DOTS PER MM. RESOLUTION AT SPEEDS UP TO 15 CM/SEC; BUT FELL SHORT OF BECOMING… more
Abstract:THE AMERICAN ASSOCIATION OF PHYSICS TEACHERS DEVELOPED PHYSICS: CINEMA CLASSICS (PCC) VIDEODISCS. THE VIDEODISCS CONTAIN VIDEO CLIPS AND FILM LOOPS WHICH EDUCATORS HAVE SUCCESSFULLY USED FOR DECADES. RESEARCHERS ARE DEVELOPING ANCILLARY MATERIALS TO ENHANCE THE ACCESSIBILITY OF THE VIDEODISCS FOR… more
Abstract:THE MISSION OPERATIONS DIRECTED AT USAKA OFTEN INVOLVE COMPLEX TARGET CONFIGURATIONS UNDER OBSERVATION BY NUMEROUS RADARS, OPTICS SENSORS, AND TELEMETRY STATIONS. IN NON-NOMINAL MISSIONS, AND IN COMPLEX NOMINAL MISSIONS, THE REAL TIME ACTIVITIES UNFOLD RAPIDLY WHICH TAXES THE ABILITIES OF THE… more
Abstract:THIS WORK REPRESENTS AN EFFORT TO ESTABLISH A MATERIALS CHARACTERIZATION FACILITY AT SYNCHROTRON RADIATION SOURCE WHICH CAN BE UTILIZED ON A FEE-FOR-SERVICE, PAY-AS-YOU GO BASIS BY INDUSTRIAL RESEARCH, DEVELOPMENT, AND PRODUCTION ORGANIZATIONS. THE ULTIMATE OUTCOME OF THE PROGRAM IS THE EXISTENCE… more
Abstract:Boron Neutron Capture Therapy is a two component modality. It is based on selective deliveryof a boronated pharmaceutical to cancerous tissue, followed by irradiation with thermal neutrons andsubsequently captured by the boron nuclei. A collaborative effort will be undertaken to develop aneutron gun… more
Abstract:Conduct a research effort to determine feasibility of developing a video imaging system consisting of TV camera, transmitter and battery packaged in a volume typical of the explosive warhead fill of submunitions such as SFW, SADARM and WAM. the goal is to be able to gun launch, canister, or… more
Abstract:XYBION PROPOSES TO CONDUCT A DESIGN STUDY TO DETERMINE THE MOST EFFECTIVE APPROACH TO DEVELOPING AN AIRBORNE COASTAL DATA MANAGEMENT SYSTEM (ACDMS). THE ACDMS WILL BE USED TO CONTROL AND INTEGRATE THE DATA FROM A COLLECTION OF AIRBORNE REMOTE SENSING INSTRUMENTS PREVIOUSLY DEVELOPED FOR NOAA UNDER… more
There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
